Novel selective ceramic-supported thin polyimide films produced in a single dip coating step are proposed for membrane applications at elevated temperatures. Layers of the polyimides P84®, Matrimid 5218®, and 6FDA-6FpDA were successfully deposited onto porous alumina supports. In order to tackle the poor compatibility between ceramic support and polymer, and to get defect-free thin films, the e...

PURPOSE We conducted a genome-wide association study to identify genetic factors that contribute to the etiology of heterophoria. METHODS We measured near and far vertical and horizontal phorias in 988 healthy adults aged 16 to 40 using the Keystone telebinocular with plates 5218 and 5219. We regressed degree of phoria against genotype at 642758 genetic loci. To control for false positives, w...

Myocardial infarction and stroke are known complications of general anesthesia, resulting in the effort to perform carotid endarterectomy (CEA) for high-risk patients under local/regional anesthesia. However, there few data supporting this practice. The ACS-NSQIP CEA targeted database was used identify all who underwent non-emergent from 2012 2021. Only were selected. High-risk defined as those...

This study used a novel integrated technology of ceramic supported carbon membrane (CSCM) to degrade azo dyes through an anaerobic mixed culture. The CSCM worked simultaneously as biofilm support, redox mediator, and nano-filter enhance the dye decolorization efficiency. Acid Orange 7 (AO7) was initially investigated with without microorganisms in both support (CS) reactors. bioreactor (B-CSCM)...

در این تحقیق به بررسی اثر ذرات MIL-53، بر خواص غشای ماتریمید در جداسازی دی¬اکسیدکربن/متان، پرداخته شده¬است. از MIL-53 که یک چارچوب آلی فلزی با حفراتی با ساختار ویژه بوده و گزینش¬پذیری قابل توجهی نسبت به گاز دی-اکسیدکربن دارد، به عنوان افزودنی استفاده شده¬است. به منظور بررسی ساختار غشاهای شبکه آمیخته با ترکیب درصدهای مختلف از ذرات MIL-53، غشاهای مورد نظر به دو روش متقارن و نامتقارن ساخته شدند. س...

In this work, mixed-matrix membranes (MMMs) for gas separation in the form of thick films were prepared via the combination of the polymer Matrimid® 5218 and activated carbons (AC). The AC particles had a mean particle size of 1.5 μm and a mean pore diameter of 1.9 nm. The films were prepared by slow solvent evaporation from casting solutions in chloroform, which had a varying polymer–AC ratio....
